To all whom it may camera:

-Be it known that "I, JENs M. JENsEN,

a citizen of the United States and resident of-Racine, .in the county of.Racine and State of Wisconsin, have invented new and usefulImprovements in Radiator 'Construc: tions, of which the following is a description, reference being had to' the accompanying drawings, whichare a part of this spec ification. r V i T s i The present invention relates to certain new and useful improvements in radiator constructions of that type particularly r of parts substantially as hereinafter deadapted for use upon tractors, automobiles and similar engine driven vehicles, and

which may also be employed" with other classes of machinery or apparatus, where it is desirable to cool liquids or fiuidsby 7 providing a means for'increased radiation of heat. r p I This invention has for one of its objects to provide anovel and simple construction of radiator including a plurality of v'erti cally, trending water passageways separated. by transverselyextending air passageways,

the air passageways having means positioned therein whereby the air passing, therethrough will be given a tortuous move mentjto cause the same to engage against the walls forming the water passageways. A further object of this invention is to provide a plurality of substantially verti- .cally trending water passageways'provided with transverse corrugations therein forming transverse air passageways with the adjacent corrugations therein provided with pro ections struck and having inserts therefrom to form deflecting surfaces in the airpassageways for imparting a tortuous movement tothe air as it passes therethrough.

'With the above and other objects in view,

which. will appear as the descriptionproy ceeds, my invention resides in the novel construction, combination and arrangement scribed and'more particularly defined by the appended claim, it being understood th-at'such changes in the precise embodiment 1 of the herein disclosed invention 'may be inadeas come within the scope of the claim. In the accompanying drawing I have ,il

lustrated one complete exampleof the physicalembodiment of my invention construct-v ed according to the'best mode have so.

' :fardevised for practical application of l the principles thereof, and in which:

Fig. '1 is-a front'viewfof a portion bra radiator construction embodying my inven tion, v Fig. 2 1Sf3i'VleW' part n sectionand part 7 in elevation taken on the Fig. 3 a fragmentaryperspective view of a portion of. one of thevertically trending water passageways and air passageway inserts.

Referring nowjimore particularly to the 'i I drawing,the numeral-5 indicates a. radiator having an .upper water compartment or' anus ivr. agmas nnoi'nnpwrsooitsriil plane indicated by line -72 of Fig. 1, and 1 tank 6,12 lower water compartment (notv shown), and a plurality of substantially vertically trending water. tubes 7 forming passageways connecting the upper and BIYWater compartments. 1 I r The waterntubes'l' are provided with horizontalortransverse corrugationsv8 and are opposite corrugations; of adjacent water tubes forming substantially transverse air,

positioned as depicted in Fig. l with the passageways 9. Each adj acen'tpair of tubes 7, have securedtherebetween aninsert or plate 10 which plate has projections or ears 11 alternately struck' from opposite sides thereof'and so inclined as to provide a pluin each air passageway 9. 1

' When the projections 11 are struck'from the inserts,- an opening 12 is formed which permits the air to readilypass fromoneside rality of, deflectingsurfaces positioned withv of the inserts to-the other. As will be read Y ily apparent to those skilledin the art to Which an invention of this character 'ap- I pertains, the air passing into'the passage' ways 9 is deflected by the projections l'land thrown by centrifugal force. against the walls of the tube "7, thenpasses on in eddying currentm'which eddying movements-of;

:the'air is maintainedby theffollowing pro-' 1 jectionslL- The inse'rtslO not only, serve to cause the air to travelineddying currents', but also the heat from the water. 7 I That I claim asfinyrinvention is A radiator comprisinga plurality of pairs i providean extra 'cooling fin for absorbing of n'es'tedwater tubes formed with lateral 7" projections which are sofarranged that; the

projections-of one, tube of ,each pair co-operatelwitli those L of 'the other tube so that a plurality of air passagewaystherehetween are pror ided, and a, plateinterposed between the tubes of each "pair, said plate having alternately disposed fins struck thererl roln' thereby providing a] plurality of openings in said, plate through which the air currents may pass, said fins being alter,

nately inclined With respect to the vertical,

whereby the respective air currents are directed upwardly and downwardly Yas they pass from one side of the plate through the openings therein-t0 the other side of the plate.

In testliho'ny whereof, I affix rny signature.
